This telescope was built in 1917 and took over 11 years due difficulty hauling all the components up Mt. Wilson Toll Road. The glass mirror weighs around 9,000 pounds and remains the largest solid glass mirror ever made. This was the largest telescope until the 200" telescope was built on Palomar Mountain.
